Self-drilling screw 5.5X25 (1.75–5.25 mm) 7504K zinc-plated

A self-drilling screw is intended for joining two or more sheets together and for mounting sheets to various structures. It enables fast and efficient fastening without separate pre-drilling in most applications. A self-drilling screw is especially suitable for sheet metal work and other installations where secure, durable, and practical sheet fastening is needed across different material combinations on construction sites and in industrial use.
